Summary
This study observed three cases of eccrine poroma showing malignant transformation. Carcinoembryonic antigen (CEA) staining helped identify the tumor origin, aiding diagnosis of these skin neoplasms.
Area of Science:
- Dermatopathology
- Oncology
Background:
- Eccrine poromas are benign adnexal neoplasms.
- Malignant transformation of eccrine poroma is rare but clinically significant.
Observation:
- Three cases of eccrine poroma with features suggestive of malignant change over many years were analyzed.
- Observed progression from in situ Bowenoid dysplasia to invasive squamous carcinoma.
Findings:
- Strong cytoplasmic carcinoembryonic antigen (CEA) staining in cells surrounding and forming neoplastic ducts and clefts was a key diagnostic feature.
- CEA staining helped distinguish the eccrine poroma origin of the malignant changes.
Implications:
- Dermatopathologists must carefully evaluate eccrine poromas for signs of malignancy.
- Early detection of malignant transformation in eccrine poroma is crucial for patient outcomes.
